FLOOR-Barista Applicaten filed April G,

This invention relates to an attachment .tor floor brushes for applying a sweeping compound to thetloor in advance o'i the brush.

The principal objects ot the in to provide such an attachment nith a hopper tor the sweeping compound having a valve which can be o aenedand closed readily and lett in regulated position so as to deposit the proper proportion oi" sweeping compound on the floor and to provide the same with means for readily attaching it to the baclr ot'ra floor brush and detaching it therefrom as desired. ll`he invention also involves improvements in details oi: construction as will appear.

Reference is to be had to the accompanying drawings in which- F ig. 1 is an end vievv' of a floor brush withy preferred embodiment o1 this invention applied thereto;

Fig. 2 is a plan of 'the attachment showing the brush in dotted lines;

Fig. 3 is a transverse sectional view of the hopper and attachment; and

Fig. 4 is a bottom plan view ot the hopper.

This attachment is designed to be applied to a floor brush having a horizontal back such as the back shown in Fig. l. VThis back is provided with a handle 11 and the attachment is applied on the opposite side oi the baclr from the handle.

The attachment consists mainly ot a'hopper 19 iitted on the rear to conform to the shape of the convex back and project beyond it, so as to be ot' a general hopper shape. At the bottom, which is the smallest part of the hopper, is a bottom plate 13 having a series of pertorations 1d. lit also has below it two guides l5 arranged horizontally. Between these guides and the bottoni 13 is a slide or valve 1G having pertorations 17.

The slide, when moved cica-rin, brings all the perfor-ations 1s. and 17 into registration with each other so that the floor compound can be discharged through them. lil/*hen pulled out b y its handle 18 into the position shown in Fig. a, the periorations are brought out ot registration as the space between the perforations is at least as wide asy one ot the perforations. it cansbe brought out only to this position on account ot a stop 19 at the opposite end so when pulled clear ont as 'far as it can go the operator ltnovvs that it will be in working orner.y ,ll-le can maire his adjustments as desired,

rihe top 20 ot' the hopper is hinged at the outer edge and 1 catches under a central spring 21 which acts as a latch to hold it frictionally in closed position. This cover is provided with a handle 22 and it can be swung open by force applied thereto and closed inthe same way withouty releasing any latch with the other han/d.

The hopper is provided with a pair 'of inwardly extending spring members 23'7at its inner side ada ited to move under theedge ot` the back 10. Y t is also provided with spring latches 24- projecting over the back ot' the brush and having inwardly extending projections 25 adapted to spring in under this edge of the back as shown in Fig. 1 to hold the device in position. The springs 24 can be made integral if desired with a strip 26 which extends along the back of the hopper and receives t-hey edge ot the cover 2O when closed'.

In use the floor brush is employed in the ordinary Way but the valve plate 16 being moved out to open it the saw-dust compound is supplied to the floor by bringing' the brush down on the floor to produce a slight j ar. It is naturally a moist compound and Will not riced very much, it any, Without this Vbeing done. it' it does feed Without this jar action, the valve is closed a little to make the available openings smaller.

The device is applied to and removed from the back in an exceedingly simple manner being merely presseddown on it and the springs 24 it necessary forced down to apply it and being removed by pressing on the pro- `iections 25.

lThis constitutes a very simple device for the purpose intended and one that can be applied very easily and when in position will always have the -floor compound rea-dy to be `applied to the floor and adapted to be de posited thereon simply by jarring it as by bringing the brush down on the .floor with a slight blow. y Y.

Although I have illustrated and described only a single form of the invention, I am aware ont the tact that modiicationscan be made therein by any person skilled in the art Without departing from the scope of the "invention as expressed in the claims. Therefore, l do not Wish to be limited to all the details oi' construction.V herein shown and vdescribed, but what l do claim is :-Y

l. ln an attachment tor a floor brush, the Y combination with a hopperI for receiving a sweeping compound, said hopper being detachab'liy mounted? toi the back of the brush and positioned to dispense said compound in advance of the brush7 said hopper having a. bottom provided with a series of perforations and Witha pair of guides located horizontally but spaced from the bottom below it7 of a valve slidably located bet-Ween the guides and the bottom and having a series of perforations so located that when. the slide is forced in as far as it can be the peri'orations in the slide and bottom Will be out of. registration, the slide having a projection at one end for manipulating it and a stop at the other end for stopping it with the perforations in Wide open posit-ion.

2. In an attachment fora floor brush, the combination with a Vhopper for receiving a sweeping compound., mounted to dispense said compound in advance of they brush and having a valve by which the bottom can be opened to provide for a deposit of a small portion thereof on the Hoor and a cover on the hopper hinged thereto, of a strip along the edge ottl the hopper having a` spring latch for holding the cover closed, and a spring extending from the hopper at each end and a pair of spring latches conforming to the shape ofthe brush back and projecting over it to the opposite edge and having pro'- jections adapted to swing in under the opposite edge of the brush back to hold it in position.

In testimony whereof I have hereunto ait'- iXed my signature.
